Description

Flash boiling steam humidifier

Technical Field

The invention relates to the technical field of household appliances, in particular to a flash-boiling steam humidifier.

Background

The humidity belongs to one of main parameters of ambient air, is closely related to life and production of people, people live in an environment with 40-70% of humidity and feel comfortable, and people feel damp and stuffy when the humidity is higher and feel dry when the humidity is lower.

The mucosa is dehydrated and the health is adversely affected when the film is kept in an environment with low humidity for a long time; yarn breakage is easy when the humidity of the textile industry is lower than 40%; the humidity of the tobacco industry is higher than 70 percent, and the cigarettes are easy to mildew when being made. Static electricity is easily generated when the humidity of the microelectronic manufacturing environment is lower than 30%, and the quality and safety of products are extremely unfavorable. Therefore, the humidifier product can be applied to many fields.

At present, the humidifying modes mainly comprise a boiling water vapor generation technology, a spray humidifying technology and a wet film water evaporation technology:

1. the boiling and humidifying technology is mainly an electric heating humidifier, water is heated by electric energy to be boiled to generate steam, and vaporized water molecules enter air to be humidified.

The electric heating humidification technology comprises an electrode type and an electric heating type: the electrode type humidifier inserts an electrode into a water tank to be electrified, current is changed from positive to negative, heated water is a conductive resistor, and under the action of the current, the water is heated by the current to generate steam; the tubular heater is immersed in the water tank to directly heat water, the water in the whole water tank is heated to boiling to generate water vapor, and the water in the whole water tank is heated to boiling to generate water vapor, so that the energy waste caused by ineffective energy consumption exists.

No matter the electrode type humidifier or the electric heating type humidifier needs to heat water in the water tank to a boiling state, the electrodes and the tubular heater are easy to generate scale on the surface after being used for a long time, and the electrodes or the tubular heater after generating the scale not only consumes energy, but also continuously attenuates the humidifying capacity and consumes more and more energy.

2. The spray humidifying technology is that water at normal temperature is atomized under the action of pressure, and atomized micro water drops are dissociated in the air to absorb heat in indoor ambient air to form water vapor.

The spray humidifying technology comprises the following steps: pressure jet atomization humidification technology, centrifugal spray humidification technology, ultrasonic humidification technology and the like. The pressure jet atomization humidification technology, the centrifugal spray humidification technology and the ultrasonic humidification technology are all that water drops form water mist which flies in the environment, and the water mist is vaporized after absorbing heat in the environment, for example, the ultrasonic humidification technology atomizes the water into 1-5 micron ultra-micro particles, the water mist is diffused into the air, after absorbing the heat in the air, the water mist is vaporized, and the vaporized moisture is diffused into the air, so that the humidification purpose is achieved.

The spray humidification technology atomizes water drops, all of which need to absorb heat in the environment to form water vapor, and in the humidification process, water flies in the air in the form of molecular clusters or particles to easily form a breeding source of bacteria, and the tiny water drops scatter on dust and articles to provide breeding conditions for various microorganisms, and rapidly breed at a proper temperature, so that the elderly, children and other weak people are easily infected after being inhaled, and the clinical medicine is called as 'humidifying pneumonia'. Research shows that the water in the ultrasonic humidifier is easy to breed bacteria and pollute the ambient air, and the number of the bacteria is gradually increased along with the continuous service time.

3. The wet film water evaporation technology is an enthalpy humidification mode, and can cool and purify air. The wet film is mainly divided into an organic wet film type, an inorganic wet film type and a metal wet film type according to the material of the wet film.

The wet film evaporation type humidifying technology is that a water distributor is used for spraying water above a wet film and the water flows downwards along the wet film. On the surface of the wet film, water and air are subjected to heat and moisture exchange, and the water absorbs heat and is gasified and evaporated, so that the air is humidified and cooled.

The wet film evaporation type humidification technology has the defects that a fan and a water pump power machine are needed, the size is large, the wet film needs to be frequently replaced, a water tank needs to be frequently cleaned and replaced, otherwise bacterial pollution and mildew are easily caused, the environment is polluted, forced airflow humidification is needed, the water pump is pressurized, the noise is high, the flow rate of the environmental airflow is high, and the comfort is poor.

In cold seasons, the water mist sprayed into the air can be vaporized only by absorbing the sensible heat of the air, so that the ambient temperature is reduced, and the heat supply load of indoor heating is increased.

Therefore, a new humidification technique is required.
